ALLEN PARK -- For weeks, most draft analysts figured the Detroit Lions would select an offense tackle with the fifth pick of the 2013 NFL draft, but by the time the Lions were on the clock, the top three tackle prospects were already off the board.

General manager Martin Mayhew told the media he had conversations about trading up and down from the fifth spot, but insisted the athletic pass-rusher wasn't a consolation prize.

Coach Jim Schwartz admitted the Lions still has work to do to address the unit responsible for protecting franchise quarterback Matthew Stafford.

"We have a long way to go," Schwartz said. "We drafted Riley Reiff last year. We have a lot of confidence in Riley. Riley played a game for us, started a game for us last year and did a good job there. He looks better this year than he did last year. We have other young players across the line and we still have a lot of draft to go."

Schwartz reiterated that the team is comfortable and confident with Reiff starting at left tackle next season.

"That's why we drafted him," Schwartz said. "That's why we drafted him last year, and when Jeff (Backus) got hurt for that one game, that's why Riley went in and played."

The Lions hold the No. 36 pick in the second round of the draft. Among the offensive lineman who could still be available are offensive tackles Menelik Watson and Terron Armstead and offensive guards Justin Pugh, Kyle Long or Kyle Warford.
